Another thread on this forum discusses various aspects of multilingual stores. Yesterday someone posted a link to Sphero's website (http://www.gosphero.com), Sphero provides a multi language support by using multiple shopify stores. One for each language they support.

"Also for certain things such as Click + Collect you can always accept the order before the Shopify Checkout and just feed the data directly from the product pages if they are paying in store or for pre-order."

Yourshops (https://yourshops.io) will create an in store delivery option for you. And, it is fully integrated with Shopify. Not only that, it also attracts in store traffic to your local store when customers looking for your products in Yourshops marketplace.
